Concept Questions
Question #1

Glucose molecules form rings. The first carbon atom creates a hemiacetal with the fifth carbon atom to make a pyranose (6-membered) cyclical structure.

In which of the links below do you find a description of this process?

Link-#22 Link-#63 Link-#87 Link-#39

Question #2

Examining the three dimensional shape of the organic molecule cyclohexane can tell us a lot about the three dimensional shape of a glucose molecule.

In which of the links below is the role that cyclohexane plays in determining the optimum structure of the glucose molecule in space discussed and described?

Link-#79 Link-#17 Link-#14 Link-#46

Question #3

Chiral objects have the property of "handedness", meaning they can be "left handed or right handed". Although they may have the same purpose and properties, these pairs of objects are not quite the same, in a very special way.

In which of the links below are the special properties of chiral objects described and explained?

Link-#88 Link-#21 Link-#03 Link-#54

Question #4

Glucose is a good example of an organic molecule that can have a single molecular formula, but several different structural formulae. This was demonstrated by Emil Fischer in the 19th century.

In which of the following links is there a description of Fisher's ideas and what it means for the glucose molecule?
